The Honourable Artillery Company (HAC) was incorporated by royal charter in 1537 by King Henry VIII, and is now a registered charity whose purpose is to attend to the "better defence of the realm". Armoury House is the Mess for the HAC — The oldest regiment in the British Army. The striking blue and yellow colour scheme of the Queen’s Room creates fabulous energy. The huge windows overlook Artillery Garden and there is a series of impressive portraits — including one of a young Queen Elizabeth II
